Besides having a good cover, a striking and/or memorable title is one of the best ways to get people to take a further look at your book, maybe even the actual words inside. Past titles that have caught my attention in such a manner include THE DIRTY PARTS OF THE BIBLE and DEATH BLIMPS OF DOOM!
Here's the newest one to catch my eye: DIE YOU DOUGHNUT BASTARDS by Cameron Pierce. This falls into the "Bizarro" genre, which is kind of anything-goes, weird, weirder, weirdest combination of magic realism minus the realism, mixed with the brown acid from Woodstock and frequently with a large dose of tastelessness as well. (Pierce is also the author of ASS GOBLINS OF AUSCHWITZ, frequently cited as an exemplar of Bizarro fiction.) Not really to my taste, so I probably won't ever read the book, but I do love DYDB's title; I get a smile on my face every time I read it.
And I note from the latest LOCUS magazine that a fellow named Sam Munson has a book titled THE WAR AGAINST ASSHOLES coming out from Saga Press next year. Another great title, but, dammit!, now I have to come up with a different title for the autobiography I thought I might write someday.
So what are your favorite book titles?
